I bought Komplete 6 and then upgraded to komplete 7, which has quite a lot of plug-ins and the price is very resonable.
i use it with cubase 6
just started though and cant say much
but as much as i can see there are posibilities for synthesis, making your own freaky sounds, bass, drums, the full monty..

Just had a buddy loan me his Maschine....loving it on Traktor and finding a fair number ov tutorials and templates. I like that you can memorize Maschine more like software than just a controller. Nice to have the lid shut or screen go dim from actually working this appliance.
